The Admiralty wanted <a href="/wiki/William_Denny_and_Brothers" title="William Denny and Brothers">Denny</a> to produce a design that was suitable for pre-fabrication construction to enable large numbers to be built.<sup id="cite_ref-1" class="reference"><a href="#cite_note-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup> </p><p>They were the largest of the Coastal Forces vessels, and were the only ones to be built of steel (to meet the fast production requirement – all other Coastal Forces craft were of wood). They resembled a miniature <a href="/wiki/Destroyer" title="Destroyer">destroyer</a>, and were perhaps the most graceful of all the craft produced during the Second World War. However their comparatively large silhouette was a drawback, making them too easy a target for the faster German craft.<sup class="noprint Inline-Template Template-Fact" style="white-space:nowrap;">[<i><a href="/wiki/Wikipedia:Citation_needed" title="Wikipedia:Citation needed"><span title="This claim needs references to reliable sources.

Steam had the advantage of quietness but demanded a large hull. Large wooden hulls were not feasible for mass production, so steel was used. This meant hulls and machinery were beyond the scope of the small yards engaged in the rapid expansion of the coastal forces, and the SGB thus competed for berths in yards already hard put to produce urgently required convoy escorts. Also they competed in the demand for mild steel and steam power plants against the more urgently demanded destroyers; accordingly the planned 51 further vessels were not ordered, and the two units ordered from <a href="/wiki/John_I._Thornycroft_and_Company" class="mw-redirect" title="John I. Thornycroft and Company">Thornycroft</a> were not completed after air-raid damage.

A disadvantage was that, while a petrol boat could start from cold and get away immediately, the SGB had to remain in steam. Over time the addition of 18 mm (0.7 in) protective plate over the sides of the boiler and engine rooms, together with the extra armament and crew, increased the displacement to 260 tons and their service speed was consequentially reduced to 30 knots.<sup class="noprint Inline-Template Template-Fact" style="white-space:nowrap;">[<i><a href="/wiki/Wikipedia:Citation_needed" title="Wikipedia:Citation needed"><span title="This claim needs references to reliable sources.

There were a pair of (57 mm) six-pounder guns fore and aft, and two twin Oerlikon 20 mm cannons, one in the apex of the bow and one on the stern superfiring over the three-inch gun.

These were usually called "escort minesweepers". However, with a maximum speed of 24 knots they were much slower than the steam gun boats.<sup id="cite_ref-3" class="reference"><a href="#cite_note-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup> </p> <div class="mw-heading mw-heading2"><h2 id="Service">Service</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Steam_gun_boat&action=edit&section=2" title="Edit section: Service"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>A lack of steel and turbines meant that the 52 boats initially planned were reduced to an order of nine boats which received the designations SGB 1 to 9.
